I feel this v;ill develoD into a very powerful tool if people will just add to it as they work on various species and oapers. I would recommend that everyone write the ON citation number on papers in their working library to facilitate indexing. One section of this job winch could easily be done would be to compare the species names found Ln and after ON" citations already printed and add them to a copy of the list above." Anyone willing to add 'to the index above will receive a free copy of the updated list to work from including updates done by myself and other peoDle. fhe next listing for this index will definitely not come before 1982 and may be in 1983 so the best way to get one is by adding to the list yourself. In addition to the bribe, this will prevent too much duplication of effort. Please send deletions for any names which are not opisthobranchs as defined in the Kkirch, 1981 issue of the Opisthobraneh Mewsletter on page n. The same information will be useful for any previously cited papers which do not include opisthobranchs. If anyone is interested in adding another journal series to the list here, please drop me a note so that we do not have three people Jo PURCHASED '^y U^ ■^ ; OPISTHOBRAMCH NEWSLETTER indexing the Nautilus, for example. EDITOR'S NOTE The next necessary index is a cross reference between ON citation number and the volume and page numbers where the most complete citation appears in the ON. Examples are given here. 10000 13:25 10001 13:25 10002 13:25-26 10003 13:26 I should be able to print this listing at least 4 columns across the page by 80 lines down. This will yield 320 references per pa^e. Since there are about 6000 citation numbers it will take aLmost 20 pages to print them all, but, the list should allow people to find things quickly and easily. Deleted references would simply not appear in the next edition of the index, I would appreciate reader comments on the need for such an index and I would especially like to have a volunteer to do the job. All you need is a complete set of the Opisthobraneh Newsletter. 1 doubt that many people even notice and most probably do not care but the amount of information in each page of the Opisthobraneh Newsletter has more than doubled since the early issues.

This is my Christmas newsletter. 198I has been a real growth year for me and, I think, for the ON. Merry Christmas to all of you and thank you for your continued support and friendship. It has kept me going for a lot of years. Anyone travelling through Los Angeles is welcome to call or drop by. Much of the time there will not be anyone at ray house so please do use the answering machine (433-7148). I will definitely get back to you as soon as possible. I work very close to Los Angeles International Airport and would be happy to come over and see any of you even if for a stopover on a longer flight. I sell microfilm equipment and supplies for Datacorp (213/679-0473) and am in the office most of the daytime. Please feel free to call if you can't catch me anywhere else. I may not be able to talk for a long time but I will be pleased to hear from you. My daughter, Kristin, is now 13 and will be with me for the Christmas holidays. She is doing well in school and growing into a very pretty young lady. My mother, Ruth, has recovered almost completely from her strokes last year and is living in the house at 36I Roycroft. Thank you all for the Christmas cards and letters. 1 hope that this Christmas is as nice for you as it is for me. Thanks to Dr. P.L. Phung for proof reading the Poizat paper below. Thanks to Jim Lance, Don Cadien, Ron Velarde, Dave Behrens, Dr. Baba, Eveline Marcus, and others who have provided material for this issue. I have a volunteer to cross-index the back volumes of the ON. Are there any volunteers for specific journal runs? I really do not want to print an index before it is reasonably complete so let's get several journals into the next species index. If anyone notices non- opisthobranch names creeping in please notify me at once. The suggestion has been made to rearrange some of the names by taxonomic placement. I do not want to list names except as actually cited. Any taxonomic placement changes may be noted in brackets after the original name. They will also show up as the new combination in alphabetical order within the list. OPISTHOBRANCH NEWSLETTER PERSONAL NOTES December, 198 1 Volume 13, Number 7, Page 40. PAPER From Dave Behrens: "I spent a week, October 3-9, 198I collecting in Bahia de los Angeles, Baja California, Mexico. This is of course the infamous collecting spot of James Lance who on numerous occasions has collected several dozen species on a single trip (see previous ON issues). Jim s collections have always been during spring and summer months, so we were anxious to see what was present during this time of year. The findings are noteworthy. After 5 days of heavy sampling only two opisthobranch species were collected, Berthellinia citrena and Tridachiella diomedea. No nudibranchs were observed. Several additional observations were made which may later assist in explaining this dramatic seasonal shift: 1) surface water temperature was 78°F, below 15 feet - 76°F, and 2) the usual dense benthic algal crop (primarily Ulva & Sargassum) was entirely absent." From Dr. Kikutaro Baba: "During the last part of this year 1 had been working on the Dendrodorididae and part of the Dorididae, and obtained a number of subjects not hitherto defined well. In the next year I hope I will be able to prepare MS of some papers for future publication. Dr. Eveline Marcus, Caixa Postal 6994, Sao Paulo, Brazil, 01000, has sent some additons to the generic name list. I had an enjoyable evening with Don & Kathy Cadien a week or so ago. They are doing well. I also ran into Ron Miracle at a gathering on the l8th of December. It is good to be living in Southern California again although I miss the great collecting around Pismo Beach, California. From Dave Behrens: "Platydoris macfarladi Hanna, 1951 lives. Two large specimens recently collected in Southern California. Behrens and Bob Henderson to publish redescription and eco notes, soon." From Bob Henderson (Pacific Bio-Marine Labs, Inc., P.O. Box 536, Venice, CA 90291) in reference to Platydoris macfarlandi: "We got photos of the living animals as well as the actual sponge substrate they were living on. Dave and I are putting the final touches on a redescription complete with photos." "I'm interested in finding out whether anyone else has run across incidences of color attenuation or loss as a function of increasing depth. I've collected a few specimens of deep water Archidoris which seem to point to this trend but not anywhere near enough to make any claims. I'd be -'.aterested in any input on Archidoris or other dorid species." Modifications morphologiques et fonctionnelles d'un mollusque raarin Microhedyle milaschewitschii Kow. 1903, au cours d'une contamination in vitro par le mercure. by C. Poizat, M. Henry & G. Cristiani Nos etudes ecologiques des Gasteropodes mesopsammiques montrent que ces animaux prosperent dans des biotopes peu ou pas pollues. II nous est done apparu utile d'effectuer sur I'une des ces especes, des experiences de contamination in vitro par le chlorure mercurique. Ce derive a e'te choisi, d'une part, parce que la pollution mercurielle de la mar est des plus preoccupantes, d'autre part, parce que les caracteristiques physico- chimiques de Hg Clp sont bien connues. Nous avons suivi les modifications morphologiques et fonctionnelles des animaux a la suite d'une contamination unique, a des taux de Hg respectifs de 0,00012 (temoin) ; 0.008 ; 0.02 ; O.O8 ; 0.1 ; 0.5 ; 1 et 2 mg/1. Pour des valeurs <: 0.08 mg/1 (doses subletales), les animaux presentent une serie de modifications physiologiques et structurales: - stade 1 : perte d'activite et d 'adherence au support ; - stade 2_ : lyse des organes sensorials et contorsions ; - stade 3. • rupture de la parol du corps et hernie des visceres. Ca stada irreversible est le critere de letalite retenu. - stade 4^ : les animaux ayant survecu (168 heures a des taux) ^0.08 rag/1 sont capables de regenerer totalement leurs organes sensoriels et reprennent un comportement normal. Dans certains cas, les regenerations sont anarchiques, avec formation de tumeurs. a des taux > 0.1 mg/1 (dose letale) les stades 1 et 2 sont tres fugaces et meme inexistants aux plus fortes doses, les specimens pouvant attaindre directeraent le stade 3 en une heure. A ce stade, I'etude par microscopie photonique et elactronique montre la lyse de 1 'epithelium tegumentaire de I'animal, dont nous savons qu'il est son organe de respiration cellulaire ou de 1 'osmoregulation at ce, a des taux relativement faibles (DL 50 = O.O8 mg Hg/1, a 20 h.), ce qui nous conduit a considerer Microhedyle milaschewitschii comma une especa tres sensible a la pollution mercurielle et a I'utiliser comma indicataur biologique. OPISTHOBRANCH NEWSLETTER READER FORUM December, 198 1 From Sandra Millen: "I was thrilled with the genera list in the latest O.N. I noticed there were a few species included but not even all of those found in The Veliger. I would like to see species listed with their most recently recognized genera and with the author and publication date after each. They then could be cross listed to journals. People could then make additions and deletions and synonymies as they saw them.

PERSONAL NOTES From Kathe Jensen: "1 am presently working as Visiting Assistant Professor in the Division of Science and Mathematics, College of the Virgin Islands. [Charlotte Amalie, St. Thomas, U.S. Virgin Islands 00801] I have only been here for about 5 weeks^[as of 25 February, 1982], and haven't had much time to go collecting, because 1 have been too busy getting everything ready for the courses I teach, finding a place to live, finding a reasonably priced dependable car (if there is such a thing), and having my stuff shipped over (some all the way from Denmark and some from Florida). However, I have done a little collecting from the beach right outside the College and have found Elysia tuca, Elysia serca (=E. clena), Cyerce antillensis, and Calliphylla mediterranea. I hope to be able to do more extensive collecting when all practical obstacles have been dealt with." From Jeff Hamann: "1 spent two weeks collecting opisthobranchs with my family in Australia this Christmas. We went to Lizard Island on the Great Barrier Reef. It's really a neat place. We had near perfect weather and an ideal set-up. Making sometimes 3 dives a day we burned 65 tanks of air, hit about 25 spots including 4 on the main reef and never got cold! Collecting was the best I've ever seen. We found 75*different species of opisthobranchs. I got passable photos of 72 and brought home some preserved material. Unlike Heron Island (we spent Christmas 1978 there), where large Chromodorids were out and about all over during the day, collecting was hard work. Most specimens were under subtidal rocks and few were encountered more than once. At Heron Island there were 20 or so large dorids that were fairly common but only one Elysia, 1 Aglaja & Chromodoris decora could be called common at Lizard Island. Best depths seemed to range from intertidal to 30' at Lizard Island and 40' to 60' at Heron Island. In spite of these differences and over 1,000 miles I found 23 species common to both places." From Steve Long: "Talked with Sandra Millen on 2-23-62. It snowed in Vancouver yesterday. I am heading up to Eureka to see the Oringers on the 27th of February and then on to see Sandra around the 3rd of March for a few days. Plan to look at Vancouver Island while there. I will be back in Long Beach by March I4th.
